Dino Rhamph is a legendary, phoenix-like Dino Knight whose pterosaur form is a Rhamphorhynchus. Dino Rhamph is the most powerful of the Dino Knights and, per Dino Brachio, can even control life force. At one point Diamond Ryugu harnessed Dino Rhamph's power for a weapon. When freed with Kaito, Rena and Rick, he merged with Dino Tyranno to help him defeat Diamond Ryugu. Afterwards, he separated from Dino Tyranno and flew off.
